iPaperFree looks bare bones on the surface, but it works well as a straightforward document reader and sharing tool for your iOS device. It doesn't have the sheer level of support that some other reading apps offer, but with single-page sharing features and quick loading from e-mail or linked accounts like Dropbox, it works well to load and read documents on the go.
iPaperFree has two major functions: loading and reading your documents and sharing bits and pieces of those documents with people from your device. You can load documents either from other apps or from an in-app menu that links with Dropbox, Mail, iTunes and other file-storing systems on your iPhone. Documents are added to an iBooks-style interface where they can be moved, edited, or deleted. Tap any to load it and you can read it on your device, with load times being fairly quick, though large PDFs may still take some time. The major feature this app has that others don't, and one reason we really liked it, is that you can mail someone a single page of a document as you are reading it, a very useful tool, especially in business settings.
While the free version has limitations of only five documents at a time and there are certain other restrictions related to sharing and how you view the documents, iPaperFree is a solid app that works well for what it offers. For a full-feature document reader there are more powerful apps, but this one is good for sharing and general reading in a quick and free interface.
